Proxies\__CG__ error ?

[tamert]

Only one record exploded this error

The form's view data is expected to be an instance of class Proxies__CG__\App\Entity\UserLevelTranslation, but is an instance of class App\Entity\UserLevelTranslation. You can avoid this error by setting the "data_class" option to null or by adding a view transformer that transforms an instance of class App\Entity\UserLevelTranslation to an instance of Proxies__CG__\App\Entity\UserLevelTranslation.

Why one record " instance of Proxies__CG__\App\Entity\UserLevelTranslation." ? I have no idea

Hi, this might be impossible to fix without real code. Could you provide pull-request with test case to reproduce?

I change static::class in \Knp\DoctrineBehaviors\Model\Translatable\TranslatableMethodsTrait::getTranslationEntityClass to self::class and it works. Makes sance. In tag 1.6.0 there was __CLASS__.

@burrag Thank for the solution

With the latest 2.6.2 this is not solved,you need to use self instead of static in referred above case. Here's some debug output what happens:

self::class: App\Entity\Location
static::class: App\Entity\Location

As you can note, the static keyword resolves the class name before it is initialized properly to a Proxy class instead of actual entity.
